The Lowdown
Alright folks, Rusty here. The only game in town for the next couple of weeks is Jaconé, and it's got a real mixed bag of a forecast. The water is sitting at 73°, which is pretty much spot on for this time of year, nothing unusual there.
The first real standout is Tuesday morning, August 25th. We've got a solid 8ft S swell, a 14-second period, and a clean, cross-offshore E wind at 9 mph. The energy is pumping at 2698. This is proper, powerful groundswell. That size and period will be firing at Jaconé, but it's not for the faint of heart. The wind and tide will be favorable, but this is a big, powerful wave – definitely one for the experienced crew only. It's a classic setup that'll have the bowls offering up some serious lines.
Wednesday morning, the 26th, is another beauty. The swell drops a touch to 6ft from the S, but the period is a solid 12 seconds and the wind is a glassy 3 mph from the W. The energy is at 2049. This is the kind of morning you dream about – clean, glassy, and with plenty of power. The 6ft is still a sizeable wave, so it's not for learners, but for anyone with a bit of experience, this is the pick of the week. The sets will be well-spaced with that long period, making it a bit easier to get out the back.
There's a bit of a gap in the quality after that. Thursday morning the 27th is still good with a 8ft S swell and clean offshore winds, but the energy is a bit lower. From Friday the 28th, the swell really drops off, with small, weak energy and short-period windswell. The weekend of the 29th and 30th sees some bumpy, short-period ENE swell, but the winds are clean. It's rideable, but nothing special.
The next real window to watch opens up on Wednesday, September 2nd. The afternoon looks promising with a 8ft SSW swell, a 12-second period, and a clean cross-offshore breeze. The energy is solid at 1642. This is another one for the experienced surfers. Then on Thursday the 3rd, the swell eases into the 6ft range with a 12-second period and light offshore winds, making for a very good, clean session.
The rest of the first week of September is a mix of smaller, cleaner days and some bumpy afternoon breezes. The standouts in that second week are the glassy mornings. Saturday the 5th and Monday the 7th both have glassy, light winds and 6ft S swells, perfect for a long, clean surf. The 14th of September also looks glorious with a glassy, 4ft S swell and zero wind. It's a smaller day, but it'll be a rippable, fun wave.
The bottom line: Jaconé is the only spot, and it's got a few absolute crackers. If you're an experienced surfer, get on the Tuesday the 25th or Wednesday the 26th morning. For the rest of us, the glassy mornings in early September with the 6ft S swell will be the best of the rest.
Rusty.

Information about the Jaconé Surf forecast
The above surf forecast table for Jaconé provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Jaconé can be found by selecting the local surf guide option on the grey menu. Our Jaconé surf forecast is unique since it includes wave energy (power) that defines the real feel of the surf rather than just the height or the period. If you surf the same spot (Jaconé) regularly then make a mental note of the wave energy from the surf forecast table each time you go. Very soon you may start to choose your surf days based on the wave energy alone combined with our forecast of favourable offshore wind conditions. Our star ratings will help here and of course you will also find the usual wave height and period predictions on our surf forecasts as well as a full break down of the swell components under our advanced users option (to reveal that, click the little Einstein character under the tide times).
Further information to help with frequently asked questions about our surf forecast for Jaconé may be found under the help tab on the top menu and also by moving your mouse over the question marks on the surf forecast table itself. Please always bear in mind that the forecast is for near-shore open water and local factors at each surf break influence the actual breaking wave height, such as the beach / reef profile, water depths offshore and shelter.
